             Summary: Graph-based Sorter Attempting Inserts in Wrong Order
                 Key: CAY-2688
                 URL: https://issues.apache.org/jira/browse/CAY-2688
             Project: Cayenne
          Issue Type: Bug
          Components: Core Library
    Affects Versions: 4.2.M2
            Reporter: Peter Hvass


Stack trace below - the graph-based sorter appears to be trying to insert a child before a parent - but this is happening non-deterministically (i.e.: some sessions & some users it happens - others not). I haven't managed to reproduce it myself directly - just pulling logs from errors our users have faced today in production. :)

I'm not sure of the extent of the info you might need relating to the affected part of the schema - entities at play - let me know and I will update accordingly and very much happy to help investigate further.
